Why is a Regular W204 Transmission Fluid Change So Important?
Imagine driving your W204 through scenic roads, but suddenly your automatic transmission shifts roughly and jerkily. A nightmare for any car driver! The most common cause of such problems is used transmission fluid.

- Smoother gear changes
- Improved fuel efficiency
- Longer transmission life
